Being an on-the-go mom is hard enough BEFORE you add in fitness and possible romances with One Direction's Harry Styles! LOLz!

Kimberly Stewart seems to be taking it in stride, though, whether or not the latter is all the way true!

Even as a busy-bee mom, Kimberly has been taking her health very seriously, keeping up with it the best that she can! Here (above), she's seen leaving Tracy Anderson Studios after getting her fitness on!

We're not sure we'd wear a denim vest to work out in, but hey, that's just us!

Shane Redway -- a Canadian rapper and close friend of Drake's -- was killed early Saturday morning in a car crash. He was just 26 years old.

Redway and two others were killed when their car lost control, struck a guardrail and burst into flames. The crash occurred around 4am outside Pearson International Airport in Toronto. It's unclear who was behind the wheel. Police are investigating the crash.

Drake took to Instagram to remember Redway, posting two different tributes.
